Reaction Mechanism – Organic Chemistry

When an alkyl halide reacts with the base then an elimination reaction occurs and an alkene is obtained as a product. 
The reaction is as follows:

C₂H₅Br+ KOH(alc.)  → C₂H₄ + KBr+H₂O 

The mechanism of the reaction is as follows:

The other reactions are as follows:

CH₃CH₃+Cl₂ → CH₃CH₂Cl+ HCl ( Free radical substitution reaction)
CH₃Cl+ KOH(aq.)  → CH₃OH +KCl (nucleophilic substitution reaction)
CH₂=CH₂ +Br₂  → CH₂BrCH₂Br (electrophilic addition reaction)

1. Oxidising Reagent = number of oxygen atoms should be more

2. Peroxide or Superoxide bonds.

Fenton’s reagent is a solution of hydrogen peroxide (H₂O₂) with ferrous iron (typically iron(II) sulfate, FeSO₄) as a catalyst that is used to oxidize contaminants or waste waters.

 Osmium tetroxide (OsO4) is widely employed as a catalyst in various organic reactions.

The acidified potassium manganate(VII) solution oxidizes the alkene by breaking the carbon-carbon double bond and replacing it with two carbon-oxygen double bonds
